Patent DE-2812235-A1 (DE)
Title: Tablet compressive strength test rig - with two load cells in opposite directions recording fracturing force
Inventor: EGGERT WINFRIED ING GRAD
IPC: G01N3/08
Filed: 1978-03-21
Abstract: The parent patent described a test rig to determine the compressive strength of tablets by applying to them a force until the tablet fractured and by measuring that force by a load cell on a back-up element. This supplied reliable results only for the same tablet dia. or thickness. In this addn., this weakness has been remedied by using instead of the one load cell and back-up lever an articulated lever and two load cells. The new lever is hinged at the top and articulated in the centre, with the two parts acting on load cells in opposite directions.

Title: Freewheel coupling for engine transmission - has driving member guided by clamping body faces rotating on different axis
Inventor: AMMON WILFRIED VON DIPL PHYS
IPC: F16D41/04
Filed: 1978-05-31
Abstract: The freewheel coupling has two clamping bodies (11, 12) with pressure faces not symmetrical in relation to the coupling axis. One of these bodies is coupled to one of the coupling shafts, and by these faces they define in the freewheeling position a common rational axis different from that of the coupling. A driving member (15), positively coupled to the other shaft, on gimbals or by gear teeth, rotates freely on this axis in relation to the bodies, being guided by the faces. There can be two clamping bodies rotating on the driven shaft and for a limited amount in relation to each other. The driving member is guided so that when freewheeling it rotates about a different axis (16). Limited rotation of the bodies in relation to each other grips the driving member between them and transmits the drive to the shaft (7) to which the member is coupled.

Title: Wall fixing anchor bolt - has expanding sleeve secured by tightening forward section of nut which breaks off when bolt is secure
Inventor: FISCHER ARTUR DR
IPC: F16B13/04
Filed: 1978-10-02
Abstract: The anchor bolt (3) is intended for securing a component e.g. (5) to a wall. It comprises a sleeve (1) which locks the bolt in a bore in the wall by being expanded. This expansion takes place under the action of a taper (2) when a nut (6, 7) on the protruding end of the bolt is tightened. The nut has a forward portion (7) which is intended for engagement by a spanner and is connected to its rearward portion (6) via a fracture line. When the torque on tightening reaches a given level, the portions (7, 6) separate, leaving the bolt with portion (6) in position.

IPC: A61B5/107
Filed: 1979-05-19
Abstract: The support for a patient's foot is designed to apply an upwards force to enable X-ray photographs to be made to detect fractures between the shin bone and ankle bone. The patient's leg rests on the surface (16) of the couch, secured by a leather strap, with the foot supported against the two faces at right angles in an L-shaped carrier (20, 21). This rests against an intermediate surface (19) connected to a fixed support (25) parallel to it, by two swinging levers (22, 24). These are connected to each other at four hinge points forming a parallelogram linkage. The upper lever (22) has an extension (26) on the other side of its hinge point (28) carrying a sliding wt.

Title: Antitheft system using keyboard of radio receiver - is for entering numeric code which disables antitheft measures when correct code is used
Inventor: BREITSCHWERDT WERNER PROF DIPL
IPC: B60R25/045
Filed: 1979-08-07
Abstract: The antitheft system has the keyboard belonging to a radio receiver connected to a coder when a special switch is operated. A numeric code can then be entered via the keyboard and if found to be correct disables the antitheft system. The radio receiver may be controlled by a microprocessor which may also be used by the antitheft system. The ignition circuit of the vehicle remains open until the correct code is entered at the keyboard. When the correct code has been entered the ignition can be closed via the keyboard. A timing circuit ensures that the code must be entered within a given time.

Title: Frictionless ball-mounted, radially-movable workpiece test cylinder - has swivelling cylinder caps and radially-movable cups
Inventor: RISCH HANS
IPC: G01N3/10
Filed: 1979-11-10
Abstract: A hydraulic test machine for traction, pressure bending and buckling testing of workpieces under static and dynamic loading has a frictionless ball-mounted, radially-movable test cylinder with play-free rotation which adjusts itself to the shape of the test piece under load. Each cylinder cap (11,11') has a ball-shaped outward surface mating with a cup (12,12') in the bearing cap (13,13'). The cylinder (3) press. rise, in proportion to the support area (8,8') and piston surface area, causes a rotation of the cylinder caps (11,11'). The cylinder caps and cups (12,12') are supported hydrostatically and the dead wts. are compensated by corresp. variations in surface area ratio. In a multiple cylinder arrangement each cylinder contributes equally to the load bar inclination.

Title: Roller blind on building window - has elastic flap resting resiliently against surface of varying diameter blind coil
Inventor: REGIUS EMIL ERWIN VON
IPC: E06B9/17
Filed: 1979-11-14
Abstract: The heat insulating flap is fitted on roller blind assemblies which have been built on existing windows. The flap is of an elastic material fitted with one edge to the slat provided on the upper window frame leg. The flap is shaped in such a way, that it constantly rests against the surface of the coil of the roller blind preventing heat from escaping through the gap which occurs, when the roller blind is lowered and the dia. of the blind coil is at its minimum. Without the flap, heat from the air space between blind and glazing would escape through the gap and slot between the outer surface of the blind and cover plate.

Title: Spray tubes for wet treatment of filament tows, etc. - having tangential impact plate converting sprays into liquid curtain
IPC: D06B1/02
Filed: 1980-02-20
Abstract: In equipment for the continuous wet-treatment of continuous material, partic. continuous filament tows, the material passes meander-fashion around two sets of rollers, one above the other, with between each upper and lower pair of rollers a series of jets spraying liquid under pressure onto the material. The spray issuing from a jet is directed initially against an impact plate which spreads the jet into a widening film which merges with those from neighbouring jets to form a continuous, uniform curtain across the width of the machine which flows down the plate and gently over the material without disrupting the filament arrangement. This is a simple and economical method of producing a continuous liquid curtain which treats the two, etc., gently, avoiding filament entanglement and subsequent breakages.

Title: Hoisting device with braked winch - has switch element to increase braking action at end of travel
Inventor: DOLINSEK HANS
IPC: F16D65/28
Filed: 1980-03-21
Abstract: The hoisting device can be a lifting crane or a scraper with a winch which has a brake whose braking force is created by an energy store which so acts on the brake via a spring to tension the spring. An operating element can move from a braking position into a release position against the force of the energy store to reduce the tensioning of the spring and to reduce the braking effect. A switch element is operated by the operating element in its release position to increase the braking action of the brake (11,12). This switch element is operable shortly before or at the end of the operating path of the operating element (29).
